well, if immigration have already flagged you, it will be totally up to the immigration officer, at point of entry, whether to let you in or not. Most probably, your name is down in the system already....good luck
check with your embassy/consulate. If you want to play games with immigration, it's totally up to you. Many countries get 60 days + 30. You could leave, and enter again for a further 60+30.....if Immigration officer will allow that
